for Fastening Carpet to Concrete Floors, of

which the following is a specication.

My invention has for its ob]ect the prolviding ofinexpensive and effective means by which carpets may be securely fastened at their edges on concrete floors atan economic cost.

I carry out my invention by provldlng wooden strips secured in position by metali lic tie strips, the latter being anchored in the wall. 'And I concealthe edge of the carpet by means of a shoe molding, so a's to present a harmonious aspect to the e My invention embodiesv further ticular features hereinafter fully described.

In the accompanying drawings constituting a part of this specification: Figure l is a sectional elevation, in perspective, of a portion of a partition wall and its floor base, showing my invention as applied to such construction; in this view the carpet and iiller areomitted; Fig. 2 is a sectional elevation, in perspective, of an exterior wall and its floor connections, showing my invention as applied tothe edges of a room abutting on such exterior wall; Fig. 3 is al diagrammatic sectional elevation, showing a different method of anchoring the metallic" tie stri in wall or floor; Fig. 4 is another mode or accomplishing the same result; Fig. 5 is a sectional elevation, in perspective, of a wooden carpet nailing strip, showing the recess which may be used in order to bring the top of the metallic tie strip flush with the top of carpet nailing strip; and Fig. 6 is a diagrammatic sectional elevation illustrating theuse' of a wooden car' pet nailing strip having a flat level top.

a and o represent a partition wall and an prising the usual plaster grounds b, plaster face c, wire ducts d, and mortar joints e.

f is a woo-d base, g a wooden shoe, k represents fragmentsyof carpet, and i the carpet ller.

On the nished surface, m, of the concrete floor, n, is placed a carpet nailing strip, j, running entirely around the edges of the is secured in place by le, which are anchored parl crete floor, in a building,

in the floor or wall and bent back over and conformed to the upper surface of said nailing strip, to which said turned back p0rtions are nailed. 1' is a mol-ding topping the wood base. Recesses p may be cut in the carpet nailing strip, if desired, so that the top of the metallic tie strip will4 be flush with the surface of said carpet nailing strip. The top of the carpet nailing strip may also be made with a level surface, as shown at s (see Fig. 6) and the tie strip j conformed thereto, so that the tension of the carpet will be horizontal, which is more advantageous than a construction whereby the pull'is not at right angles to the restraining means.

For edges abutting partitions the construction is as follows: While the mortar in the mortar joint is still green, the fiat metallic tie strips are inserted under the plaster grounds. After the wood base is in place a carpet nailing strip (j, lai-d against the base of the wall, as shown, and the metallic tie strip, c, is bent back over and nailed to the4 former, as shown in Fig.`1. vThe carpet ('72.) is laid over the carpet Iiller (i) and is nailed to the carpet nailing strip, as illustrated in Fig. 2. The shoe molding, g, is then placed in position, and the beveled base of same serves to hold the carpet in place and also to conceal edges of same.

For edges abutting, or exterior walls, the metallic tie strips, k, are laid on the rough concrete floor, n, and embedded in the concrete finish m. The metal strips'l being formed and arranged in either of the modes shown in Figs. 2, 3, or 4, for the purposeof anchoring same. In other respects the procedure is just the same as above. The described methods may also be used at the base of columns. A plurality of tie strips place, and they are placed convenient distances apart.

1. The combination with a wall and conof a tie strip anchored at the base' of the wall, a nailing strip laid against the base of floor, the tie strip superimposed upon the nailing strip, and a molding aiixed to the wall and restingupon said nailing strip.

2. The combination with a wall and concrete floor, ina building, of a tie strip anchored at the base'of the wall, a nailing strip are used vforsecuring the nailing strip iny such wall on the laid 'against'.the base of such Wall on the floor, the tie strip superimposed upon the nailing strip7 and means holding down that side of the nailing strip abutting against the Wall.

3. The combination with a Wall and concrete floor, in a building, of a plurality of metallic tie strips anchored at the base ofthe Wall, a nailing strip laid against the base oi such Wall on the floor, the free ends of tl1e tie strips being bent back over the nailing strip, and a molding ailixed to the Wall and resting upon said nailing strip.

4. rl`he combination with a Wall and concrete iloorfin a building, of a plurality of 15 nailing strip, and means holding down that 2o side of the latter abutting against the Wall.
